Q:What are the different methods of protecting steel pipes from corrosion?: There are several methods of protecting steel pipes from corrosion. One common method is coating the pipes with materials such as epoxy, polyethylene, or fusion bonded epoxy, which create a barrier between the pipe's surface and corrosive elements. Another method is cathodic protection, which involves using sacrificial anodes or impressed current to prevent corrosion. Additionally, applying corrosion inhibitors or using corrosion-resistant alloys for manufacturing the pipes can provide protection. Regular maintenance, including inspections and cleaning, is also crucial to ensure the ongoing protection of steel pipes from corrosion.

Q:How are steel pipes handled and transported safely?: Steel pipes are handled and transported safely by following certain procedures. They are usually lifted and moved using cranes or forklifts that have the appropriate capacity to handle their weight. To prevent damage during transportation, pipes are secured in sturdy containers or bundles, often by using straps or chains. In some cases, protective coverings or caps are used to shield the ends from any potential damage. Additionally, proper stacking techniques are employed to ensure stability and prevent accidents during transportation.

Q:What's the actual size of the DN25?: DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)

Q:What is the difference between hot-finished and cold-finished steel pipes?: Distinguishing hot-finished and cold-finished steel pipes can be done by examining their manufacturing processes, which lead to different characteristics and applications. To create hot-finished steel pipes, a solid steel billet is heated to a high temperature and then pierced to form a hollow tube. This process, known as hot rolling, ensures that the steel is easily shaped and malleable. As a result, hot-finished steel pipes have rough surfaces and rounded edges. They are generally larger in diameter and have thicker walls. These pipes are commonly utilized in industries that demand high strength and pressure resistance, like the oil and gas sector, structural projects, and heavy machinery manufacturing. On the other hand, cold-finished steel pipes are produced using a process called cold drawing. This involves pulling the hot-finished steel pipe through a die at room temperature to reduce its diameter and achieve the desired shape. The cold drawing process yields a more precise and smoother finish for the steel pipes. Cold-finished steel pipes possess smoother surfaces and sharper edges compared to their hot-finished counterparts. They are typically smaller in diameter and have thinner walls. Cold-finished steel pipes are commonly applied in industries that require accurate dimensions, such as automotive part manufacturing, construction component fabrication, and machinery production. In conclusion, the primary disparity between hot-finished and cold-finished steel pipes stems from their manufacturing processes, resulting in variations in surface finish, dimensions, and applications. Hot-finished pipes are suitable for applications that demand high strength and pressure resistance, while cold-finished pipes are ideal for applications that require precise dimensions and smooth surfaces.

Q:When can I use the PVC pipe and when to use the galvanized pipe?: PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.

Q:What is the average lifespan of steel pipes?: The average lifespan of steel pipes can vary depending on various factors such as the quality of the steel used, the environment in which they are installed, and the maintenance and care they receive. However, on average, well-maintained steel pipes can last anywhere from 50 to 100 years or more.

Q:What is the difference between steel pipes and plastic pipes?: The main difference between steel pipes and plastic pipes lies in their material composition. Steel pipes are made from a durable and strong metal alloy, while plastic pipes are composed of various types of plastic polymers. This difference in materials leads to variations in their properties and usage. Steel pipes are known for their high strength, resistance to extreme temperatures and pressures, and longevity, making them suitable for applications requiring robustness, such as in industrial settings or underground pipelines. On the other hand, plastic pipes are lightweight, flexible, and corrosion-resistant, making them ideal for plumbing, irrigation, and other non-industrial applications. Additionally, plastic pipes are easier to install and handle due to their lighter weight and flexibility compared to steel pipes.

Q:What are the different types of steel pipe end connections?: Some of the different types of steel pipe end connections include threaded connections, socket weld connections, butt weld connections, and flanged connections.

Q:Are steel pipes suitable for use in food processing industries?: Yes, steel pipes are suitable for use in food processing industries. They are highly durable, corrosion-resistant, and can withstand high temperatures and pressure. Additionally, steel pipes are easy to clean, maintain hygiene standards, and do not contaminate the food being processed.

Q:Can steel pipes be used for hydropower systems?: Yes, steel pipes can be used for hydropower systems. Steel is a durable and strong material that can withstand high pressure and corrosion, making it suitable for carrying water or other fluids in hydropower systems. Additionally, steel pipes can be customized to different sizes and shapes, allowing for efficient water flow and distribution within the system.
